In addition the APSA port provides space for receiving the wireless device for activation and communication in the secondary Ethernet-like wireless communication system. The golf club head may be a wood or an iron. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99-40:60 at a temperature of 25 C.
